No, the car could be traveling up an incline at constant velocity for example.sr_philosophy said:You are in a car and there is a pendulum suspended in front of you. You have no idea of what is going outside, i.e., you are completely blind from the surroundings. You can see only the pendulum and the interior of the car which has nothing else. You find that the pendulum is at the beginning straight down and later you find that it is bending towards you. (I hope you understand) Can you conclude that the car is accelerating?

there is no possible scientific experiment you could do to discover weather it is gravity pushing you to the side of the room, or if you are simply accelerating
http://en.wikipedia.org/wiki/Bill_UnruhThe Unruh effect, which Unruh discovered in 1976, is the prediction that an accelerating observer will observe black-body radiation where an inertial observer would observe none. In other words, the accelerating observer will find himself or herself in a warm background.
Acceleration is the rate of change of an object's velocity over time. It is a vector quantity and is measured in units of meters per second squared (m/s^2).
In a car, acceleration can cause objects to move at different speeds and in different directions. This can create blind spots, where objects or other vehicles may be moving in a way that is not immediately visible to the driver.
A pendulum demonstrates acceleration through its swinging motion. As the pendulum swings back and forth, it experiences a constant acceleration due to gravity, which keeps it moving in a circular path.
The factors that affect acceleration include the initial velocity, the mass of the object, and the forces acting upon the object. These can include gravity, friction, and other external forces.
Acceleration can be calculated using the equation a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time. This equation is based on the average rate of change of velocity over a given time interval.
